Explanation:

Given that;

  the compound contains nitrogen and oxygen in the ratio 1:1;

       We can say the compound is NO

Now,

Molecular mass of NO;

 Molar mass of N = 14g/mol

 Molar mass of O = 16g/mol

Molecular mass of NO = 14 + 16  = 30g/mol

This can be fixed by multiplying the product contacting nitrogen by 2. o The new chemical equation is N2 +H2 →2 NH3 Reactants Products Nitrogen 2 2 Hydrogen 2 6 Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3.

They propagate in materialistic media and non-materialistic media ( space ) .

They propagate in the space at constant velocity , which is 3 × 108 m/s .

They consist of vibrating electric and magnetic fields at certain frequency in phase with each other , perpendicular to each other and perpendicular to the direction of the wave propagation ...

Explanation:

welcome!

The properties of electromagnetic waves are the electromagnetic waves are propagated by oscillating electric fields and magnetic field oscillation at right angles to each other, These waves travel with speed 3×108ms−1 in vacuum. Therefore, option A and B are correct.

The term electromagnetic waves or EM waves are defined as the waves that are produced as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are made up of oscillating magnetic and electric fields.

They are created in different processes and are detected in different ways, but they are not basically different. Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation.

Thus, option A and B are correct.

Answer:

[tex]\%LiClO_3=90.4\%[/tex]

Explanation:

Hello!

In this case, since the undergoing chemical reaction is:

[tex]LiClO_4\rightarrow LiCl+\frac{3}{2} O_2[/tex]

It is widely known that when a gas given off from a reaction is collected over water, we can compute its pressure by minusing the total pressure 762 mmHg and the vapor pressure of water at the experiment's temperature (20 °C) in this case 17.5 mmHg as shown below:

[tex]p_{O_2}=762mmHg-17.5mmHg=744.5mmHg*\frac{1atm}{760mmHg}=0.980atm[/tex]

Next, by using the ideal gas equation we compute the yielded moles of oxygen considering the collected 313 mL (0.313 L):

[tex]n_{O_2}=\frac{PV}{RT}=\frac{0.980atm*0.313L}{0.082\frac{atm*L}{mol*K}*293.15K}\\\\ n_{O_2}=0.0128molO_2[/tex]

Now, via the 3/2:1 mole ratio between oxygen and lithium chlorate (molar mass = 90.39 g/mol), we compute the original mass of decomposed lithium chlorate as follows:

[tex]m_{LiClO_3}=0.0128molO_2*\frac{1molLiClO_3}{3/2molO_2}*\frac{90.39gLiClO_3}{1molLiClO_3} \\\\m_{LiClO_3}=0.771gLiClO_3[/tex]

Now, the percentage is computed as shown below:

[tex]\%LiClO_3=\frac{0.771g}{0.853g} *100\%\\\\\%LiClO_3=90.4\%[/tex]

Luster: Metals are shiny when cut, scratched, or polished.

Malleability: Metals are strong but malleable, which means that they can be easily bent or shaped. ...

Conductivity: Metals are excellent conductors of electricity and heat.

Three properties of metals are:

Good conductors of electricity and heat: Metals have a high electrical and thermal conductivity, meaning they allow the flow of electricity and heat through them with ease. This property makes metals valuable in various applications, such as electrical wiring and heat transfer.

Malleability: Metals can be easily shaped and molded into various forms without breaking. They can be hammered, rolled, or pressed into thin sheets without losing their structural integrity. This property allows metals to be used in manufacturing processes and the creation of different products.

Ductility: Metals can be drawn into thin wires without breaking. This property makes them suitable for electrical wiring and cable manufacturing, where flexibility is required.

Answer:

A colloid is a mixture composed of particles in a dispersing medium. A colloid is defined by the size of the particles involved. If the particles in a mixture are on the scale of individual molecules, around 1 nanometer, it is defined as a solution. If the particles are larger than 1,000 nanometers, it is a suspension.

Answer:

ka = 2x10⁻⁹

Explanation:

Using the pH we can calculate the molar concentration of H⁺, [H⁺]

Then we use the expression of Ka for the equilibrium of a weak monoprotic acid:

HA ↔ H⁺ + A⁻

Where:

ka = [tex]\frac{[H^+][A^-]}{[HA]}[/tex]

ka =  [tex]\frac{(2.24*10^{-5})(2.24*10^{-5})}{0.25-2.24*10^{-5}}[/tex] =  2x10⁻⁹
